Hi all! The ExecutionConfig has some very old settings: forceAvro() and forceKryo(), which are actually misleadingly named. They cause POJOs to use Avro or Kryo rather than the POJO serializer.
I think we do not have a good case any more to use Avro for POJOs. POJOs that are also Avro types go through the Avro serializer anyways. There may be a case to use Kryo for POJOs if you don't like the Flink POJO serializer. I would suggest to remove the "forceAvro()" option completely. For "forceKryo()", I am torn between removing it completely or renaming it to "setUseKryoForPOJOs()". What are the opinion on that out there? Best, Stephan
